Water Quality Characteristics of Jeju Island in 1930s
Correspondence to : hsy@pusan.ac.kr
Abstract
In this study, the chemical components (pH, HCO3-, Cl-, and SO42-) of water sources (surface water, groundwater, and spring water) in 1930s were compared to those in the period of 1985?1992 in Jeju Island. By the comparison, pH values and Cl-, and SO42- concentrations in 1930s appeared similar to those in the second period (1985?1992) while HCO3- increased about the six times in the second period. Such a great increase of HCO3- concentration may be caused by the increase of carbon dioxide in the atmosphere due to industrialization.
Keywords Jeju Island, 1930s, water source, water quality, carbon dioxide
